Kom stands for "Keep old mails". It imports emails in a MySQL database and provides a frontend in gtk2 to search and browse the archived emails. Some options can be used to incrementally import mails (do to it each month for example). It can also export mails stored in the database, in mbox format or one-message-per-file format, and generate some statistics.

SpamOracle, a.k.a. "Saint Peter", is a tool to help detect and filter away "spam" (unsolicited commercial e-mail). It proceeds by statistical analysis of the words that appear in the e-mail, comparing the frequencies of words with those found in a user-provided corpus of known spam and known legitimate e-mail. The classification algorithm is based on Bayes' formula, and is described in Paul Graham's paper, A plan for spam.
